The easy-to-operate plastic construction LifeStraw Family is used to purify large amounts of waste water on location in the villages and families into drinking water. Central element is a plastic casing, approximately 30 centimeters in length, which contains filtering membranes made from Ultrason E. These achieve ultrafiltration (UF-membranes) and remove viruses as well as bacteria from dirty surface waters from rivers, lakes, rainwater collection barrels or even puddles.
